Re: Lamb
and Lettuce

: When a child, I sometimes
lounged around on the settee and was asked why I was sitting there like lamb and
lettuce. Does anyone know where this saying comes from?

I think you will find
that there is a variety of lettuce called "Lambs" as I have heard of Lamb's Lettuce.
If I recall correctly, a lamb's lettuce has much floppier leaves than an iceberg.
I would guess somebody misheard something like flopping around like a lambs lettuce
and changed it to lamb & lettuce.
